Phase change materials (PCM) offer a great potential to passively cool buildings by using latent heat to store the room thermal energy throughout the day and releasing it at night when the ambient air is cooler. This study ...

The energy needs of the Navy and the Department of Defense demand renewability, reliability, and resilience. Diverse means of energy production, including hydrogen gas combustion, support these requirements. The overarching ...

Research was conducted for the development of formulations for additive manufacturing of metal nanoparticles that produced a 3D printed metal object without oxidation but with material properties and corrosion resistance ...

Traditional fleet operations and technologies are not adequately suited to counter the growing threat to undersea infrastructure from autonomous undersea systems. A cost-effective unmanned and manned system of systems is ...

The use of fiber-matrix composite materials in military ordnance casings is of increasing interest to the U.S. Navy due to the potential for such casings to reduce collateral structure damage. In order to use fiber-matrix ...

The regulation of temperature within living and storage spaces in high-temperature environments is a demanding challenge mostly met using high-fuel consuming air conditioning systems. Phase-change material (PCM) systems ...

There is a growing interest in using unmanned underwater vehicles to perform a large array of tasks that require operation near the surface, and the wave-induced loads experienced by these vessels play an important role ...

Previous research at Naval Postgraduate School produced a design procedure for generating gas compressor rotor models using commercial software. This design procedure was improved upon by parameterizing the blade profiles ...

This research successfully developed and tested an improved triboelectric nanogenerator (TENG) with water waves at the Naval Postgraduate School (NPS). The copper electrode holder and track to which the PTFE tape was ...

The ability to evaluate new missile technologies and explore various flight profiles through experimental flight tests is an essential step in most technology development paths. This capability is often an expensive option ...
